I've been having issues that plogger_album_picture_count() is not returning the amount of images in an album.
It looks like mysql_result has been altered in the new PHP 5.4 I'm running and needs a row number.
On line 2808 in my plog-functions.php I changed the function call to: return mysql_result($numresult, 0, 'num_pictures'); and that seems to do the trick.
